Following his time at Cern, Haroon Mirza has been creating a major installation based on his research there. The piece, made with his collaborator Jack Jelfs, is a sculptural art work which uses a circle of eight speakers, a large screen and an octagonal chandelier sculpture of LEDs to compose light, sound and video. Combined with a careful manipulation of spatial acoustics, the viewer is cocooned in a truly immersive experience. Oonagh Cousins joins Haroon in his studio as he and Jack work on the installation, to discover the creative processes behind his art. What are the technical challenges in creating this kind of piece, which has to be reassembled in different spaces? And will the final installation and rehearsals go according to plan?
